Any number to the power of a negative integer will be 1 over that number with the absolute value of the power, so it looks like this:

x^{-2} = \frac{-1}{x^{2}}

Therefore, you just need to 8² which is 64, and then do 1 over that (1/64) because it's a negative power.

marysya [2.9K]

Answer:

33

Step-by-step explanation:

If you simplify what the question is saying, it's basically..

8 is 24% of <u>what number?</u>

To find out, you can simply set up an equation.

((24% = 0.24 as a decimal (move the decimal point two times to the left))

8 = 0.24 x N (N is just the 'whole')

To solve, you just need to divide 8 ÷ 0.24. So, N = 33.333 repeating.

The question says to round to the nearest whole number, so the answer would just be 33.
